Shelvy said her son had no major medical issues that would explain his unexpected death. She said officials also don't know what killed the Tabor City teen. It will reportedly take up to 12 weeks before a final autopsy report is available.

"Until then we cant even began to try to move on..we just need to know what happened to him," Daniels said.

A funeral will be held Sunday at 2:30 p.m. at the Deliverance Prayer Temple in Loris, SC, according to Westside Funeral Home.

Shelvy said Cephus's teammates will carry his casket and follow him into the church, while wearing their football jerseys.

They've taken the news of Cephus's death just as hard as the family.

"It was a wake up call," Quinlan Hammond said. "We all need to grow closer to God because, I mean, life could be taken from us at any second."

Friends and family gathered at Shelvy's home this week to mourn, many of them wrapping their arms around her to show their support.

"I couldn't believe it at first," Dashaun Daniels said. "Later that night it just hit me. That's when I started crying and stuff and I cried myself to sleep that night and I woke up crying. I just couldn't believe it."
